List Rules Vote up the photos that capture what is creepiest about the uncanny valley.

If you're not familiar with the concept of scary uncanny valley robots, then the wisest course you can probably take right now is to run screaming before you stick around long enough to see anything that cannot be unseen. If, however, you're among the incautiously curious or you've already been subjected to enough creepy uncanny valley pictures to find resistance futile, then you'll find more unnerving examples here. So what exactly is the uncanny valley, you ask? It describes non-human creation that is simultaneously too realistic and not quite realistic enough, like creepy CGI characters with realistic skin and hair but dead, lifeless eyes. Or a robot with a face that's not quite convincingly human.

If you're still a little confused about the concept, rest assured that you won't be for long. Here you'll find a collection of photos from the uncanny valley that should pretty much give your nightmares enough ammunition for years to come.

So strap on your seatbelts and accelerate headfirst into a non-stop trip to the uncanny valley and all the horrors it holds.
